Open Cell Spray Foam Insulation

Open cell spray foam is a half-pound density foam that expands roughly 100 times its liquid volume when applied. That expansion is what makes it so effective — it reaches into every crack, gap, and irregular surface that rigid insulation boards and fiberglass batts simply can't touch.

For Oklahoma homeowners dealing with 100°+ summers and ice storms in winter, that airtight seal matters more than R-value alone. A fiberglass batt might have a similar R-value on paper, but the moment wind pushes through gaps around it, that number means nothing. Open cell foam eliminates those gaps entirely.

Where Open Cell Works Best

Open cell is the go-to choice for attics, interior walls, and ceilings. It's softer and more flexible than closed cell, which makes it ideal for areas where the structure might shift slightly over time — like roof decking that expands and contracts with Oklahoma's temperature swings.

It also dampens sound significantly. If you've got a bonus room above the garage, a home office, or bedrooms that share walls with living spaces, open cell foam cuts noise transfer by 50% or more compared to fiberglass.

What It Costs

Open cell spray foam is a cost-effective solution compared to closed cell, making it the smart choice when you need coverage over a large area. The energy savings start from day one, and the investment typically pays for itself within a few years. Every project is different — contact us for a free estimate tailored to your specific space.

Open Cell vs. Closed Cell

The decision comes down to where you're insulating and what you need. Open cell is the better value for interior applications where moisture isn't a concern. It costs less, fills gaps just as effectively, and provides solid R-value. Choose closed cell when you need the vapor barrier properties — crawl spaces, exterior walls, or metal buildings where condensation is an issue.
